Geospatial Technologies Geospatial Technologies, which includes the technologies and principles of digital cartography, remote sensing, photogrammetry, surveying, Global Positioning Systems (GPS), Geographic Information System (GIS), and automated data capture systems.
Geospatial Technologies Geospatial Technologies provide the tools and techniques, which allows the processing and analysis of spatial data into information tied explicitly to make decisions, about portions of the earth and environmental problems. Geospatial Technologies, which include all stages of data collection, data processing, database management, data analysis and modeling and data presentation, to end use in the creation of value added maps and spatial information products.
Geospatial Technologies in Sustainable Land Management 1. Developement of digital terrain database and landform mapping 2. Land resource inventory and mapping 3. Assessment of soil loss and erosion risk zone mapping 4. Hamonization of degraded and wastelands datasets of India 5. Soil fertility mapping and assessment 6. Land use systems analysis and monitoring in different AER s 7. Spatial modeling for crop suitability and land use planning 8. Design and development of Geoportal 9. Capacity building
Why we need Geoportal? Geoportal provides a mechanism to organize and catalogue legacy datasets and enrich with new datasets maintain uniform standards in development of geospatial databases organize, catalogue, view, edit, discover and display of geospatial datasets reduce redundancies and duplication of efforts in geospatial data generation enforce consistency, standards, data sharable protocols provide mechanism to build a cross-domain knowledge based applications provide a mechanism to assess the potentials and limitations of land resources data integration to generate land use plans at various levels suggest alternative land use plans and scenarios through modeling aid in dynamic decision making process of LUP through SDSS develop prescriptive land use modules for technology transfer generate outputs in the form of thematic maps, tables and reports

BHOOMI Geoportal provides a platform to collate, organize and standardize the geospatial databases on land resources across the scales. It provides a robust platform for effective storage, process, analyze, query and visualize the geospatial data and information through interactive data analysis tools. BHOOMI Geoportal enables to develop applications and services in effective utilization of land and allied resources databases in development of site-specific geosmart agriculture land use plans in the country.
Conclusions Use of modern geospatial technologies such as high resolution satellite data, GPS and GIS should be mandatory in land resources inventory, mapping, monitoring and management at watershed level. Geospatial technologies must be effectively used in generation of digital terrain database, inventory and mapping of soils, land use systems at parcel level, soil suitability evaluation, prioritization of watershed, assessment of carrying capacity and monitoring the impacts at watershed level. Synergy must be achieved in integration of precise database in through Geoportals on land resources, socio-economic and contemporary technologies to provide a sophisticated mechanism to generate alternative action plans at different scales for sustainable land resource management and land use planning. The stake holders should be the centre of action plans to integrate their priorities and aspirations with a convergence approach in decision making to improve the productivity levels to meet ever increasing food, fodder and fuel demand to ensure food security.
